“…Recent work on MF compounds and particularly ME coupling explains ways to improve these features through the development of double perovskites [41,42], heterojunction [43,44], doping [45,46], co-doping [47,48], and modulation of different properties [49,50]. In these cases, theoretical methods have been employed to address the magnetic, optical, electronic, and structural properties of the investigated compounds; however, experimental studies have explained the improvement in the magnetoelectric coupling of the investigated compounds.…”

One of the primary objectives of scientific research is to create state-of-the-art multiferroic (MF) materials that exhibit interconnected properties, such as piezoelectricity, magnetoelectricity, and magnetostriction, and remain functional under normal ambient temperature conditions. In this study, we employed first-principles calculations to investigate how changing pnictogen elements affect the structural, electronic, magnetic, and optical characteristics of QFeO3 (Q = Bi, P, SB). Electronic band structures reveal that BiFeO3 is a semiconductor compound; however, PFeO3 and SbFeO3 are metallic. The studied compounds are promising for spintronics, as they exhibit excellent magnetic properties. The calculated magnetic moments decreased as we replaced Bi with SB and P in BiFeO3. A red shift in the values of ε2(ω) was evident from the presented spectra as we substituted Bi with Sb and P in BiFeO3. QFeO3 (Q = Bi, P, SB) showed the maximum absorption of incident photons in the visible region. The results obtained from calculating the optical parameters suggest that these materials have a strong potential to be used in photovoltaic applications.

“…Due to its outstanding electrical and magnetic properties, lithium ferrite (Li 0.5 Fe 2.5 O 4 ) has found wide applications in various fields of modern industry [1][2][3]. High saturation magnetization values, low dielectric loss, high Curie temperature, low coercive force, low cost, and high chemical stability make it one of the most popular materials in the production of different microwave devices with a wide range of applications [4 -7].…”

In this research, nanocrystalline lithium ferrite (Li 0.5 Fe 2.5 O 4 ) was synthesized using the solution combustion approach with using glycine as fuel and a chelating agent at various Red / Ox ratios ("glycine to nitrate" ratio G / N = 0.4, 0.6, 0.8, 1.0). According to the data of energy-dispersive X-ray spectroscopy (EDX) and atomic absorption spectroscopy (AAS), the prepared samples correspond in their composition to stoichiometric ferrite Li 0.5 Fe 2.5 O 4 within the error of the determination methods used. The results of powder X-ray diffractometry (PXRD) confirmed the formation of α-Li 0.5 Fe 2.5 O 4 at G / N ratio of 0.8 and 1.0 and the presence of β-Li 0.5 Fe 2.5 O 4 modification in case of deficiency (G / N = 0.4) and stoichiometry (G / N = 0.6) of the chelating agent. It is shown that a change in the Red / Ox composition of reacting solutions affects not only the phase composition of the synthesized lithium ferrite samples, but also the crystallite size, which lies in the range from 22 to 35 nm. Based on the scanning electron microscopy (SEM) data, it was found that Li 0.5 Fe 2.5 O 4 powders had a developed porous microstructure consisting of micron agglomerates. According to the vibration magnetometry data of nanocrystalline lithium ferrite powders, it follows that all synthesized compositions have a pronounced ferrimagnetic behavior, despite the presence of β-modification in some of them. It is shown that by varying the Red / Ox environment and, as a consequence, the phase composition and crystallite size, it is possible to obtain Li 0.5 Fe 2.5 O 4 nanocrystals with magnetic parameters in the following ranges: saturation magnetization (M s ) = 51.6 -61.9 emu / g, residual magnetization (M r ) =14.3 -17.8 emu / g, coercive force (H c ) =109 -135 Oe.
